1. A device for calculus fracture comprising a means for:
applying an acoustic probe to a targeted calculus mass, the probe comprising a probe tip, wherein the probe tip comprises a flat leading surface surrounding a lumen, the flat leading surface having one or more recesses extending proximally from the flat leading surface such that the probe tip has one or more pressure points for coming into contact with the targeted calculus mass, wherein the leading surface comprises a flat semi-cylindrical surface; and
sending acoustic energy down the probe to the targeted calculus via the probe tip to induce vibration of the probe tip and the one or more pressure points of the probe tip against the calculus mass,
wherein the one or more pressure points comprise a first pressure point and a second pressure point, the first pressure point being sharper than the second pressure point.
